AIR/ AND VAPOR SUPPLYI'NG AND CLEANING DEVICE FOE, ENGINES.

Application filed August 16, 1923. Serial No. 657,760.

To all whom it may concern,"

Be it known that we, Gnoncn Hanna and ALFR B. UPDIKE, citizens of the United States, residing; at San Francisco, in the county of San Francisco and State of Calitornia, have invented certain new and uselul v Improvements in. Air and Vapor Supplyl more particularly automobile engines, and

ing and Cleaning Devices for Engines; and Wedo declare the following to be a full, clear, andenact description. of the invention, such will enable others skilled in the art 'to which it appertaii' s to make and use the same.

This invention i'elatesto an mproved de vice for use in connection wlth gas engines,

it con'iprises means for conveying steam .or

vapor from the radi itor or other sources of steam to the intake manifold, either in a comparatrvely Wet state or n a dry super heated condition.

One object of the invention is togcnerally improve upon devices of this class by pro ducing one Which includes a tank in which a cleaning); liquid may be placed, whereby carbon and the like may be effectively removed from the cylinders, spark plugs and valves.

Another object of the invention isto produce a vapor supply and cleaning device VllllCllWlll first permit the cylinders, plugs and valves to be thoroughly cleaned by running theinotor, after which asupplyot vapor from the radiator or other source, may be ted to the motor to prevent formation o'i carbon to a extent.

A still further object is to provide for .feeding hot or cold auxiliary air to the m0- tor. instead of vapor, when desired.

With the foregoing; in view, the invention resides in the novel subject matter hereinafter described and claimed, certain subject matter being common to our United States application, Serial No. 4109,2755, filed Sept. 9,1920, and Serial No. 590.519, filed Sept. 25, 199m. The present applicationtherefore constitutes a continuation in part of these prior applications.

In carrying out our invention, We employ a tank tocontain a cleaningliquid when desired, a pipe or tube extending from the steam space of the radiatorto the upper end of the tank, a superheater preferably mount-- ed on the exhaust manifold or pipe of the engine piping extending from the bottom of the tank to the superhoater and inclueing a valve, a pipe or tube leading from the superheater to the intake manifold, and a valve-controlled lay-pass leading from the piping to the intake manifold, to carry the vapor from the radiator Withoutdirecting it through the superheater,Whenever desired. Provision is also made whereby hot or cold air may be supplied to the niotor. The preferred form of construction is shown in the accompanying drawings,

The numeral 1 designates a suitable tank adapted to be mounted on appropriate brackets or the like 2 which are preferably Til end of said tank having a filling plug 3 hile its lower end may Well be provided With a drain pl g L. A steam supply tube or pipe 5 leads from the st am space of the radiator to the upper end of the tank 1 and piping or tubing leads from thejlower end of. the tank to superheatcr 6which is preterably mounted. on the (Xhaust pipe of the engine. This piping, in tllfi'ffOIHi' otthe in vcntion herein disclosed, consists of a tube 7 connected to the bottom .o:t"the tank 1., another tube 8 connected to the superl'ieatt-n' 6 and a valve' vhoso valve body is indicated by the nunicral 9. From the superlicater 6, a: tubelt) leads to Y-couplino; '11 which is tapped into the intake manifold, The nutube leading from the valve body 9 to the coupling ll so that moisture may b? sent directly throiu h this tube if desired instead of sluiutingy it down the tube 8, through the sunerheater (3, and thence through the tube 10 to the intake manifold. i i

As disclosed most clearly in Figs. 3, l and 6, the valve body 9 is provided with a vapor inlet port 13 to Which the tube 7 connected, with one outlet port 1 1 from which the tube 8 extends, and with a second outlet port to which the tube 12 is connected. The body 9 is also provided with a cold air inlet nipple 13 A rotary valve 16 is located within the body 9 and is provided with a right angular port 17, whereby proper setting of the valve by means of a suitable knob 18, will permit the tube 7 to be placed in communication with the tube 6 when the superheater is to be used or with the tube 12 when it is not desired to send the vapor through said superheater. Also, the nipple 13 may be placed in communiczu tion with either tube 8 or 12 to supply hot or cold air to the engine.

The stem 16 of the valve 16 passes loosely through an opening in an escutcheon plate 19 adapted to be clamped against the rear side of the automobile instrument board, while the valve body 9 is provided with a flange 9 secured against the front side of said instrument board, bolts 9* being used. in securing these parts. The rearwardly projecting end of the stem 16 is threaded into the elongated knob 18 so that the latter may be adjusted according to the thickness of the instrument board, thereby permitting the escutcheon plate 19 to be positioned wherever desired along the stem for contact with the rear side of said board. A set screw 16 is threaded through the knob 18 for securing the knob and stem together when the necessary adjustment has been made. A coiled spring 16 surrounds the stem 16 between the tapered valve 16 and the plate 19 and always holds the valve in proper position within the body 9, regardless of any adjustment of said plate 19 along the stem 16. The valve 16 and body 9 are preferably formed with registering openings 16 (Fig. 4) through which a pin or wire may be passed to hold these parts together prior to installation.

The knob 18 is provided with an indicator 20 for co-action with the escutcheon plate 19 so that the valve may be set to supply a hot comparatively dry vapor to the engine, a wet vapor directly from the steam space without passage through the superheater 6, cold air direct from the nipple 13 through the pipe 12, or heated air obtained by placing part 17 in connnunication with the nipple 18 and part 14:- Whenever desired, the tank 1 may be filled with a cleaning liquid and the valve 16 is then set so that this liquid will be drawn from the tank through the tubes 7 and 12 to the intake manifold, from which it passes to the engine cylinders to clean the latter in the usual way. As soon as the cleaning operation is effected, hot or cold air, or wet or hot vapor may be supplied to the engine cylinders.

Since excellent results have been obtained from the details disclosed, we prefer to follow these details, but within the scope of the invention as claimed, it is to be understood that numerous minor changes may be made.
